1. A mass adapted to be implanted in the body of a subject in order to replace and/or increase a soft tissue volume, comprising a textile that includes at least two superimposed textile sheets, comprising, between said superimposed textile sheets, cells selected from adipocytes, cells capable of differentiating into adipocytes and mixtures of these two types of cells, said superimposed textile sheets are formed by an interweaving of at least two same threads, said superimposed textile sheets forming a three-dimensional structure which includes at least two superimposed surface layers formed from the superimposed textile sheets, each layer being a respective face of two opposite faces of a respective textile sheet, and both layers being joined by an interweaving of the at least two same threads connecting said surface layers, said interwoven threads form pores which pass throughout the thickness of said textile; and wherein said textile includes connection points between said surface layers corresponding to nodes or fastening areas between said threads.
